HTTP Status 504

Question

I\'m getting the following error when my win32 (c#) app is calling web services.

The request failed with HTTP status 504: Gateway timeout server response ti         


        

Answer 1

If your using ASP.Net 5 (now known as ASP.Net Core v1) ensure in your project.json "commands" section for each site you are hosting that the Kestrel proxy listening port differs between sites, otherwise one site will work but the other will return a 504 gateway timeout.

 "commands": {
    "web": "Microsoft.AspNet.Server.Kestrel --server.urls http://localhost:5090"
  },
